Description
【０００１】0001
本考案は電解コンデンサの封口に関するものであり、特に、弾性体とフッ素樹 脂による２層構造の封口部材を有する電解コンデンサに関するものである。 This invention relates to the sealing of electrolytic capacitors, and is particularly concerned with the sealing of electrolytic capacitors. The present invention relates to an electrolytic capacitor having a sealing member with a two-layer structure made of oil.
【０００２】0002
従来、電解コンデンサの封口部材としては、例えば、特公平２−３０１７０号 公報（Ｈ０１Ｇ ９／０４）に示されるように、弾性体及び非弾性体（フッ素樹 脂）による２層構造の封口部材が提案されている。 Conventionally, as a sealing member for an electrolytic capacitor, for example, Japanese Patent Publication No. 2-30170 As shown in the publication (H01G 9/04), elastic bodies and inelastic bodies (fluorine resin A sealing member with a two-layer structure made of resin) has been proposed.
【０００３】0003
電解コンデンサの特性劣化を防止し、長寿命化を図る場合には、静電容量の減 少やtanδの増大等の特性劣化の最大の原因である、駆動用電解液（以下ペース トと称す）の透過・蒸発を防止する必要がある。電解コンデンサのペーストが透 過・蒸発する可能性として、以下の３通りが考えられる。 To prevent deterioration of the characteristics of electrolytic capacitors and extend their life, it is necessary to reduce the capacitance. The driving electrolyte (hereinafter referred to as pace) is the biggest cause of characteristic deterioration such as increase in tanδ and It is necessary to prevent the permeation and evaporation of The electrolytic capacitor paste is transparent. There are three possible possibilities for permeation and evaporation:
【０００４】 （１） 封口部材内部を透過して蒸発する。0004 (1) It passes through the inside of the sealing member and evaporates.
【０００５】 （２） 封口部材とケースの境目を透過して蒸発する。[0005] (2) It passes through the boundary between the sealing member and the case and evaporates.
【０００６】 （３） 封口部材に設けられたリード線貫通孔を透過して蒸発する。[0006] (3) It passes through the lead wire through hole provided in the sealing member and evaporates.
【０００７】 上述の如く、フッ素樹脂と弾性体の２層構造の封口部材を有する電解コンデン サにおいて、フッ素樹脂は非常に透過率が小さいため、電解コンデンサのペース トが封口部材を透過・蒸発を防止する効果が非常に高く、（１）の場合は殆どな いと考えられる。また、このような電解コンデンサは封口部材の弾性体の部分で 絞り加工を施すため、（２）の場合も殆どないと考えられ、（３）が問題となる 。[0007] As mentioned above, an electrolytic capacitor with a two-layer sealing member made of fluororesin and an elastic material Fluororesin has extremely low transmittance, so it cannot be used at the pace of electrolytic capacitors. The effect of preventing permeation and evaporation through the sealing member is very high, and in the case of (1), there is almost no It is considered that In addition, this kind of electrolytic capacitor has an elastic part of the sealing member. Due to the drawing process, (2) is unlikely to occur, and (3) becomes a problem. .
【０００８】 電解コンデンサのリード線は図３に示すようになっている。即ち、電解コンデ ンサの卷取り素子（図示略）から導出される電極端子は、巻取り素子と接続され る扁平状の電極部3aと巻取り素子から導出される丸棒状の端子部3bを有している 。この丸棒端子部3bの先端には、外部引出線であるＣＰ線（Ｃｏｐｐｅｒ Ｐｌ ｙ：鉄芯を銅で被覆したリード線）４が溶接されることにより、リード線を形成 しており、ＣＰ線４が巻取り素子を収納するケース（図示略）の外に引出されて いる。丸棒部3bとＣＰ線４とを溶接接続している溶接部５は電極端子の丸棒部3b の径と同一もしくはそれ以下が理想的であるが、実際は丸棒部3bの径よりも若干 太くなる場合がほとんどである。[0008] The lead wires of the electrolytic capacitor are shown in FIG. In other words, the electrolytic The electrode terminal led out from the winding element (not shown) of the sensor is connected to the winding element. It has a flat electrode part 3a and a round bar-shaped terminal part 3b led out from the winding element. . At the tip of this round bar terminal part 3b, there is a CP wire (Copper Pl) which is an external lead wire. y: lead wire with an iron core coated with copper) 4 is welded to form a lead wire The CP wire 4 is pulled out of the case (not shown) that houses the winding element. There is. The welding part 5 that welds and connects the round bar part 3b and the CP wire 4 is the round bar part 3b of the electrode terminal. Ideally, the diameter should be the same as or smaller than the diameter of the round bar part 3b, but in reality it should be slightly larger than the diameter of the round bar part 3b. In most cases, it becomes thicker.
【０００９】 この溶接部５が絞り加工を施す部分の対応部にある場合は、絞り加工が十分に 行えないため、溶接部５が絞り加工部よりも素子側もしくはケースの開口部側に くるようにしなければならない。[0009] If this welded part 5 is located on the corresponding part of the part to be drawn, the drawing should be done sufficiently. Since this cannot be done, the welding part 5 is closer to the element or the opening of the case than the drawing part. We have to make sure that it comes true.
【００１０】 溶接部５がケースの絞り加工を施す部分よりも内側にある場合は、ＣＰ線４で 絞り加工をすることになるが、ＣＰ線４はリード線の丸棒部3bより細く、十分な 絞り加工をするには非常に強い圧力を加えなければならず、生産性が悪くなり、 またケースにも負担がかかってしまう。0010 If the welding part 5 is on the inside of the part of the case that is to be drawn, use the CP wire 4. The drawing process will be performed, but the CP wire 4 is thinner than the round bar part 3b of the lead wire, so Drawing requires applying extremely strong pressure, which reduces productivity. It also puts a burden on the case.
【００１１】 そのため、溶接部５をケースの絞り加工部分よりも外側に配置することになる が、２層構造の封口部材のリード線貫通孔の径をリード線の丸棒部3bの径と同一 もしくは若干小さくすると、ＣＰ線４とリード線の丸棒部3bを接続している溶接 部５が、２層構造の封口部材のフッ素樹脂薄板のために入りにくくなる。圧力を かけて無理に挿入しようとすれば、巻取り素子自体にストレスがかかり、例えば 、巻取り素子の電極端子と箔との接続不良が発生する恐れがある。[0011] Therefore, the welded part 5 is placed outside the drawing part of the case. However, the diameter of the lead wire through hole of the two-layer sealing member is the same as the diameter of the round bar part 3b of the lead wire. Or, if you make it a little smaller, the welding that connects the CP wire 4 and the round bar part 3b of the lead wire The part 5 becomes difficult to enter because of the fluororesin thin plate of the sealing member having a two-layer structure. pressure If you try to forcefully insert the winding element, stress will be applied to the winding element itself, for example. , a poor connection between the electrode terminal of the winding element and the foil may occur.
【００１２】 逆に、この溶接部５を２層構造の封口部材のリード線貫通孔に入りやすくする ために、リード線貫通孔の径を大きくすると、封口部材の弾性体側で密封状態が 悪くなり、特性劣化が起こりやすくなる。0012 Conversely, this welded portion 5 is made easier to enter the lead wire through hole of the two-layer sealing member. Therefore, if the diameter of the lead wire through hole is increased, the sealing state will be impaired on the elastic body side of the sealing member. It becomes worse, and characteristics deterioration becomes more likely to occur.

It is preferably 110 to 150% of the diameter of the lead wire through hole.

本考案は上述の如く構成されているため、封口部材のリード線貫通孔にリード 線を挿入する工程において、弾性体側では、弾性力により弾性体自身が広がるた めに、リード線の溶接部より小さな径の貫通孔でも、容易に挿入することができ る。フッ素樹脂側では、弾性体側よりもリード線貫通孔の径が大きいため、阻害 なく挿入することができる。 Since the present invention is constructed as described above, the lead wire can be inserted into the lead wire through hole of the sealing member. In the process of inserting the wire, on the elastic body side, the elastic body itself expands due to the elastic force. Therefore, it can be easily inserted into a through hole with a diameter smaller than the welded part of the lead wire. Ru. On the fluororesin side, the diameter of the lead wire through hole is larger than on the elastic material side, so It can be inserted without needing to be inserted.

【００１７】 図１は本考案の電解コンデンサの断面図である。電解コンデンサの巻取り素子 １はアルミケース２内に挿入されている。扁平電極部3a及び丸棒端子部3bを有す る電極端子は巻取り素子から導出され、この丸棒部3bの先端はＣＰ線４と溶接部 ５にて溶接されてリード線を形成している。アルミケース２を封口する封口部材 ６はＥＰＤＭやＩＩＲ等の弾性体6aと四フッ化エチレン樹脂等のフッ素樹脂6bの ２層構造で構成されている。そして封口部材６の弾性体6aにてアルミケース２に 絞り加工を施し、封口している。[0017] FIG. 1 is a sectional view of the electrolytic capacitor of the present invention. Electrolytic capacitor winding element 1 is inserted into an aluminum case 2. It has a flat electrode part 3a and a round bar terminal part 3b. The electrode terminal is led out from the winding element, and the tip of this round bar part 3b is connected to the CP wire 4 and the welding part. 5 to form a lead wire. Sealing member for sealing aluminum case 2 6 is made of elastic material 6a such as EPDM or IIR and fluororesin 6b such as tetrafluoroethylene resin. It is composed of two layers. Then, the elastic body 6a of the sealing member 6 is attached to the aluminum case 2. It is drawn and sealed.
【００１８】 本考案のコンデンサに用いる封口部材６の断面斜視図を図２（ａ）に示し、従 来の封口部材６の断面斜視図を同図（ｂ）に示す。[0018] A cross-sectional perspective view of the sealing member 6 used in the capacitor of the present invention is shown in FIG. A cross-sectional perspective view of the conventional sealing member 6 is shown in FIG.
【００１９】 封口部材６の弾性体6a側のリード線貫通孔7a，7bは直径０．９［ｍｍ］程度で あり、リード線丸棒部3bの直径（１．０〜１．１［ｍｍ］）と略同一もしくはそ れ以下であるが、弾性力を有するため、リード線貫通孔7a，7bよりも大きな溶接 部５でも容易に挿入することが可能である。[0019] The lead wire through holes 7a and 7b on the elastic body 6a side of the sealing member 6 have a diameter of about 0.9 [mm]. Yes, the diameter is approximately the same as or similar to the diameter (1.0 to 1.1 [mm]) of the lead wire round bar portion 3b. However, since it has elastic force, it is possible to weld larger than lead wire through holes 7a and 7b. Even part 5 can be easily inserted.
【００２０】 また、フッ素樹脂6b側のリード線貫通孔7a，7bは直径１．１［ｍｍ］程度であ り、弾性体6a側のリード線貫通孔7a，7bの約１２２［％］になっている。溶接部 ５の大きさ等のばらつきを考慮すれば、フッ素樹脂6b側のリード線貫通孔7a，7b の径は、溶接部５が容易に樹脂側に挿入できる大きさ（例えば、溶接部５の最大 値）である、弾性体6a側の１１０〜１５０［％］であることが好ましい。[0020] Also, the lead wire through holes 7a and 7b on the fluororesin 6b side have a diameter of about 1.1 [mm]. This is approximately 122% of the lead wire through holes 7a and 7b on the elastic body 6a side. welded part 5, lead wire through holes 7a and 7b on the fluororesin 6b side. The diameter of value), which is preferably 110 to 150 [%] of the elastic body 6a side.
【００２１】 基本的には、封口部材の絞り加工部に溶接部５がこなければ、リード線貫通孔 7a，7bは圧着される。従って、溶接部５が絞り加工部よりもケース開口部側に位 置していれば、溶接部５が弾性体6a内に存在してもよい。しかしながら、２層構 造の封口部材６は弾性体6aが１層構造のものよりも薄く、絞り加工可能な範囲が 非常に狭い。そのため、溶接部５は封口部材の弾性体6a側に位置せずに、フッ素 樹脂6b側に位置している方が好ましい。[0021] Basically, if the welded part 5 does not come to the drawing part of the sealing member, the lead wire through hole 7a and 7b are crimped. Therefore, the welded part 5 is located closer to the case opening than the drawing part. If the elastic body 6a is located within the elastic body 6a, the welded portion 5 may be present within the elastic body 6a. However, the two-layer structure The elastic body 6a of the structural sealing member 6 is thinner than that of a one-layer structure, and the range that can be drawn is limited. Very narrow. Therefore, the welded part 5 is not located on the side of the elastic body 6a of the sealing member, but is made of fluorine. It is preferable that it be located on the resin 6b side.
【００２２】 上述の実施例においては、封口部材６の弾性体6aの厚さとリード線丸棒部3bの 長さは略同一であるため、リード線丸棒部3bを根本まで挿入するだけで、溶接部 ５が弾性体6aを突抜けることになり、リード線と封口部材６は仮止め状態となる 。従って、弾性体6aの位置で絞り加工を行う限り、リード線丸棒部3bで行うこと になり、溶接部５の位置で絞り加工をしてしまう可能性は殆どない。[0022] In the above embodiment, the thickness of the elastic body 6a of the sealing member 6 and the lead wire round bar portion 3b are Since the lengths are approximately the same, simply inserting the lead wire round rod part 3b to the root will close the welding area. 5 will penetrate through the elastic body 6a, and the lead wire and the sealing member 6 will be in a temporarily fixed state. . Therefore, as long as the drawing process is performed at the position of the elastic body 6a, it should be performed at the lead wire round bar part 3b. Therefore, there is almost no possibility that drawing will be performed at the position of the welded part 5.
【００２３】[0023]
本考案による電解コンデンサでは、リード線を挿入する工程において、リード 線の溶接部をスムーズに封口部材のフッ素樹脂側まで挿入することができる。 In the electrolytic capacitor according to the present invention, in the process of inserting the lead wire, The welded part of the wire can be smoothly inserted to the fluororesin side of the sealing member.
【００２４】 さらに、リード線の挿入後においては、弾性体の厚さとリード線丸棒部の長さ は略同一で、且つ溶接部の突起により、リード線の丸棒部と弾性体の仮止めの効 果もある。[0024] Furthermore, after inserting the lead wire, the thickness of the elastic body and the length of the round lead wire are almost the same, and due to the protrusion of the welding part, the effect of temporarily fixing the round bar part of the lead wire and the elastic body is There are also fruits.
【００２５】 従って、封口部材の弾性体及びリード線の丸棒部において、十分な絞り加工を 施すことが可能であるため、ペーストの透過・蒸発を防止することができ、特性 劣化の少ない長寿命の電解コンデンサを提供することができる。[0025] Therefore, the elastic body of the sealing member and the round bar part of the lead wire should be sufficiently drawn. It is possible to prevent the paste from permeating and evaporating, and the characteristics It is possible to provide an electrolytic capacitor with a long life and little deterioration.
